Growatt To IOT

TLS Files

To connect to AWS IOT we need the TLS files and the AWS ATS Root CA file. Follow the steps in the Terraform README.md to get the TLS files. By default the application assumes the files are in the same folder it is running from, so just copy them over.

Get The AWS CA Certificate

We'll use the -ats endpoint. The endpoint is output to the console when the Terraform build has been completed. The -ats endpoint requires the AWS Root CA certificate from here:

wget https://www.amazontrust.com/repository/AmazonRootCA1.pem

TODO

• A fatal error in the chain should not stop the rest of the chain
• An EOF in the listen should not stop the program - instead restart (could be supervisord/docker-compose or the app?)
• Try and capture program closure and let each handler close their connections nicely
• Let user configure via ENV vars and a config file
• Commenting / tests / idiomatic Go == quality
• Correct use of pointers/references == ensure we're not over allocating (re-using structs)
• Compile and dockerfile

Questions for myself!

• Is this really a growatt service? With some doc changes it could be just a socket packet to AWS IOT program... which might have a very wide range of applications. The experiment is to refactor into something generic that you can plug in your own processing.
